DEVICE FOR; NEUTRALIZING PICKLED NOURISHMENTS AND Application filed May 15; 1922. Serial No. 561,075.

Nourishments and Fodder; and I do hereby declare the following to be a full, clear, and exact description of the invention, of which the following is a specification.

The complete neutralizing of large quantities of pickled meat, fish and the like has hitherto not been possible, and the processes. which have become known up to'the present are accompanied by a series; of wants and disadvantages which shall be removed by the invention.

Meat, fish and the like which in order to preserve them had been strongly pickled were hitherto best neutralized by placing them into flowing water. In such case'the goods were contained in receptacles which gave the water an easy access to the goods and which also. allowed the water to quickly flOWOfi again. The water intliis case li'xiv iated the salt contained in the goods. This process had however the disadvantage that also in case oi along action of the water only the outer parts directly afi ected bythe water became to a certain extent neutralized while those parts of the goods placed one on top of the other in the centre and depth, in other words the bulk of them remained tin-neutralized, as the-water was not able to act on these parts. ,The salt romaine ing within and near the middle part upon the; goods being; touched spread agaiirover the neutralized parts so that the total mass practically kept. its whole amount of salt. For certain goods, for instance, for such which are used for the manufacture of fisli meal it is absolutely essential to remove the amount of salt contained as'far as POSSllllB Without at, the same timev allowing that losses of nutrition occur. The neutralizing could be achieved by exposing very small quantities to theinfluence of flowing water.

such a process. This process has still fur ther the disadvantage that in case ot a large content of salt the neutralizing W1lll8.St-

In many cases also the' kind of the goods to be neutralized forbids the using of from 24; to 48 hoursandthat already in case of a twentydour hours treatment the goods in) consequence of the lixlviation of albumen lose at least 10% of their nutrition. It has been'ascertained from experiments thatwhen treating large quantities of goods,

the nutrition of the goods is considerably decreased in consequence of the treatment with water without the contents of salt be ing drawn off to the desired extent]. 0

' It the water used for the treatment is not of a low temperature, that is to say oh about from 5-10 degrees, but of a higher temperature, the goods perish very easily after a treatment of along duration.

All these disadvantages are according to the present invention removed bringing.

the materials to be neutralized into a receptaclejand' after having filled the latter with water subjecting the materials to the action of an agitating device, during the agitating fresh water being admitted at the upper end while at thebot-tom end of the receptacle the salt containing water is let ofi.

With the aid of this process it is possible in about from a of an hour up to Qliours to carry through a thorough neutralizing of the goodswithout an appreciable loss of nutrition occurring. The latter does not quite amount to 1%. The new process makes it possible to use the strongly pickled ofials of the fish industry and other pickled raw materials for the manufacture of fish meal.

Heretofore the raw materials for the reasons mentioned in the ,aforegoing had to be I worked up with a full content ofsalt, i. e.,

with about from 5-2072). The fodder obtained therefrom were, however, in consefor being fed out alone. They could only. be used in very small quantities as an addi: tion to the otherwise used fodder. It must be taken into consideration that for instance a pig can stand 3% of salt in the fodder only. for a short period; longer feeding periods with fodder of the content of salt mentioned usually cause the death of the animal.

By means of the new processit is possible to neutralize in the shortest time in one working operation quantities of tro1ni'2000- 3000 kg. of raw material according. to; the

size otthe receiving vessel; the quantityof",

water admitted and to the amount of power available;

The device consists of a vessel a which has preferably the shape of a vertical cylinder. The vessel has journals 6 on. the side with which it is resting in bearings 0. The vessel can be swung about the journals 6 by means of the hand lever d. The lever (Z -,is fitted .on ts lower end with a fork e whichis provided with an adjusting screw The fork 6 passes around a collar 9 affected by the screw If with the aid of the hand lever (Z the vessel has been swung about its journals 6, it can be held in any desired inclined position with the aid of the adjusting screw f and the collar 9.

To the bottom of the vessel a bearing h is fixed which receives the bottom journal of a shaft e fitted with agitating wings 5. The top end of the shaft 71 is reduced and it is here gripped by the forked part m ofa shaft 01. having the same axis as the shaft 2'. A pin 0 serves to connect the two shafts i and 'n. together. On the upper end of the shaft n is mounted a conical wheel p, which is driven by a conical wheel q fixer to the drivingshaft r. The latter is driven by a motor or by a power transmission of ,any kind.

The driving of the shaft 2' could of course be effected in another way, for instance by fixing an electric motor to the vessel (4 which by means of an intermediate gear drives the shaft 2'.

Above the vessel a, a water pipe .9 has been provided for, while at the bottom end a water offlet t has been arranged. Above the water ofiiet t is a sieve a retaining the goods so that it cannot enter the water pipe:

The sieve bottom a is removable. To the water ofllet t a siphon pipe 0 is connected. The siphon pipe may consist for instance of a rubber hose, a flexible metal pipe or of a rigid pipe being extensible and fitted with joints. For carrying the tube '0 in the present mode of construction, a series of rods w have been provided for. These rods enable a raising or lowering of the tubemouth av. Obviously any other desired adjusting device can be employed for the intended purpose.

It is intended with the arrangement and adjustability of the siphon pipe to be able to adjust at will the height of the column of water effective at the place of outflow. The higher the place of the mouth 00 is arranged, the less will be the pressure acting at the place of outflow and the smaller will be also the speed of the outflow and the total pressure of the water and of the goods to be handled on the sieve bottom a.

The process is carried out in the following manner:

After the vessel has been brought into the 'position shown in Fig. 1, it is filled with It will be observed that at first the outflowing water it can be roughly as-.'

certained when the neutralizing has reached the desired degree. 7

As soon as this stage has been reached, first the agitating device and then the water admission is stopped and the water contained in the vessel is drained away. The pin 0 is then removed, the vessel a is swung with the aid of the lever (Z and it is fixed in the desired position by means of the screw in order to be able to take the goods out easily. After the vessel has been emptied, the shaft 2' and the sieve bottom it are taken out in order to be cleaned and are replaced before the commencement of the neXt working operation.
